[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 yLnTIE3)  

"Wk K1u  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： mI
:D  
enableservice('AutomationServer', true) ygm6(+  
enableservice('AutomationServer') PR(KDwsT&l  
y,KZp2 j  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 Ln+ k_

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： cFJZ|Ld  
1. 在FRED脚本编辑界面找到参考. 4\ )WMP  
2. 找到Matlab Automation Server Type Library ts@e ,  
3. 将名字改为MLAPP ,,IK}

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 [Q6$$z92Q

1. 创建Matlab服务器。 +:

3. 在探测面追迹光线 ]^a{?2ei  
4. 在探测面计算照度 n4"xVDL  
5. 使用PutWorkspaceData发送照度数据到Matlab G&M)n*o  
6. 使用PutFullMatrix发送标量场数据到Matlab中 TC:t!:  
7. 用Matlab画出照度数据 z|S4\Ae  
8. 在Matlab计算照度平均值 eB,@oo%  
9. 返回数据到FRED中 ashVV
